Leda has awesome brothers, friends who are as allergic to emotions as she is, and a great job. She’s back in her hometown, Maybelle County, after a romantic and professional disaster three years ago in Nashville. It might not be what she planned when she was a teenager, but it’s perfect.

Or, well, it’s almost perfect. Because Leda is still angry and bitter about Nashville, and everyone knows it. She hates romance and doesn’t do relationships, and her younger brother’s trying to get her to be nicer. But she’s not nice. She even has her own hashtag: #ledagoesnuclear.

Then she sees Jamie again, when he’s between serious girlfriends, and discovers that the chemistry she’s always suspected is right there, ready to explode if she lets it.

Jamie is a serial monogamist who’s always liked Leda, but the timing’s never been right. After he sees her while they’re both single for the first time since high school, he knows he wants to be with her. Everybody knows she doesn’t date and doesn’t get serious, but he’s always serious, especially because he has a three-year-old son and a three-hour commute to get from work to Leda.

What starts out as a casual Thursday night arrangement gets messy when Leda and Jamie also have interfering friends, sad brothers, a pushy mom, an amazing son, and chemistry so intense it’s scary.
